The present invention relates to the field of pressing panels, and more particularly a pressing panel which is easy and comfortable to press.
Conventional drive panels of concealed water tanks are panels provided with single-row buttons or double-row buttons. After pushing a button, a resetting mechanism is required to drive the button back to an initial position. The resetting mechanism in the prior art generally uses elastic pieces such as flat springs or torsion springs, wherein a fixing point of each elastic piece is placed on a panel body, and a supporting point of each elastic piece is placed on the button. After pressing the button, the fixing point of each elastic piece remains unchanged, while a portion between the supporting point and fixing point starts deforming; the larger the pressing depth, the greater the deformation and the rebound resistance against the button, thus requiring larger pressing force and being uncomfortable to press.
In view of the above, the present invention provides a pressing panel with an improved connecting structure, which is easy and comfortable to press.
To attain the above object, the present invention provides the following technical solutions:
A pressing panel, comprising a panel, buttons and elastic pieces; the buttons are hinged to the panel, and each button is movable with respect to the panel through a pair of hinge shafts; each button is fixedly provided with a corresponding elastic piece; each elastic piece is provided with an elastic supporting arm extending backwards corresponding to a direction which a corresponding button moves when being pressed; each elastic supporting arm abuts the panel by elastic force; when each button moves with respect to the panel through a corresponding pair of hinge shafts, a portion of a corresponding elastic supporting arm corresponding to an abutting position between the elastic supporting arm and the panel slides; when each button is in an initial state before being pressed, the abutting position between the corresponding elastic supporting arm and the panel, compared with a position of the corresponding pair of hinge shafts, is farther away from a fixing position between the button and the corresponding elastic piece.
Further preferably, the elastic pieces are elongated flat springs or elongated elastic threads.
Further and more preferably, each elastic piece has an arched structure, and a middle part of each elastic piece is provided with a concave part; a fitting base provided with a fitting hole is formed on each button; each elastic piece passes through a corresponding fitting hole; a first end and a second end of each elastic piece abut the corresponding button and the panel respectively, wherein the concave part at the middle part of each elastic piece is fixedly fitted with a corresponding fitting base by elastic force of the elastic piece itself; each elastic supporting arm is defined by an elastic part of the corresponding elastic piece between the concave part and the second end thereof.
Further and more preferably, a guiding incline is provided for each button between the fitting base of the button and an abutting position between the button and the first end of the corresponding elastic piece.
Further and more preferably, a position limiting structure is provided on each button at the abutting position between the button and the first end of the corresponding elastic piece.
Further and more preferably, the position limiting structure is defined by a pair of first protrusions formed integrally with each button on two sides of the corresponding elastic piece respectively.
Further and more preferably, the elastic pieces are torsion springs.
Further and more preferably, each button is provided with a fixing shaft; each torsion spring is fixedly fitted with a corresponding fixing shaft, wherein a first supporting arm of each torsion spring abuts the corresponding button, and a second supporting arm of each torsion spring abuts the panel; the elastic supporting arm is embodied as the second supporting arm when the elastic pieces are torsion springs.
Further and more preferably, a position limiting groove extending along a sliding path of each elastic supporting arm is provided on the panel corresponding to the abutting position between the elastic supporting arm and the panel.
Further and more preferably, the position limiting groove is defined by a pair of second protrusions formed integrally with the panel on two sides of the corresponding elastic piece respectively.
Further and preferably, two hinging columns are provided at one side of each button at two positions spaced apart from each other respectively; each button is hinged to the panel through two corresponding hinging columns; the corresponding elastic piece is provided between the two corresponding hinging columns.
Further and preferably, the panel is provided with a front surface, and a rear surface provided on a back side of the front surface; the buttons and the elastic pieces are provided on the rear surface of the panel; accommodating windows are formed on the front surface of the panel corresponding to positions of the buttons.
Further and more preferably, the rear surface of the panel is provided with blocking hooks extending backwards; when pressing each button, each button rotates backwards to a certain degree and abuts a corresponding blocking hook, thereby being limited from further rotation by the corresponding blocking hook.
Further and more preferably, each button is provided with a convex pressing part extending towards a corresponding accommodating window.
The beneficial effects of the technical solutions provided by the present invention are as follows:
When the elastic piece is fixed onto a movable component, namely the button, a supporting point of the elastic piece is positioned on the panel body, and the elastic piece slidably abuts the panel at the supporting point; when pressing the button, the elastic piece moves along with the button; a sliding motion of the elastic supporting arm of the elastic piece effectively offsets the deformation of the elastic piece, so that the deformation of the elastic piece is small, and therefore the rebound resistance against the pressing force of the button is not large; therefore, during a pressing process of the button, changes of pressing force are small; in comparison to the prior product, the pressing panel of the present invention is easier and more comfortable to press.
To further explain the embodiments, the present invention is provided with accompanying drawings; the accompanying drawings are part of the disclosure of the present invention, which are mainly adopted to illustrate the embodiments, and explain the operating mechanism of the embodiments in accordance with relevant descriptions in the specification; with reference to the description below, those of ordinary skill in the art should be able to understand the possible embodiments other than those described herein, and the benefits of the present invention; elements shown in the figures are not drawn to scale, and the same or similar reference numerals always indicate the same or similar elements.
The following describes in details the present invention with reference to the accompanying drawings and embodiments.
As illustrated in
If the elastic pieces 30 of the present embodiment are fixed by a method as in the prior art, namely fixing each elastic piece 30 on the panel 10, with each elastic supporting arm 304 abutting a corresponding button 20, and each elastic piece 30 also rotates backwards by fifteen degrees along with the corresponding button 20; each elastic piece 30 changes in position as illustrated in
Furthermore, in the present embodiment, the elastic pieces 30 are elongated flat springs; each elastic piece 30 is in an arched structure, and a middle part of each elastic piece is provided with a concave part 303; a fitting base 21 provided with a fitting hole 211 is formed on each button 20; each elastic piece 30 passes through a corresponding fitting hole 211; a first end 301 and a second end 302 of each elastic piece 30 abut a corresponding button 20 and the panel 10 respectively, wherein the concave part 303 at the middle part of each elastic piece 30 is fixedly fitted with a corresponding fitting base 21 by elastic force of the elastic piece 30 itself, thereby achieving the assembly of each elastic piece 30; each elastic supporting arm 304 is defined by an elastic part of each elastic piece 30 between the concave part 303 and the second end 302 thereof; by adopting the aforementioned configurations, assembly and disassembly of the elastic pieces 30 are more convenient; during assembly, insert the first end 301 of each elastic piece 30 into a corresponding fitting hole 211, and then press down an arched middle part of each elastic piece 30, so that the arched middle part passes through the corresponding fitting hole 211, until the concave part 303 is fitted with a corresponding fitting base 21; at this time, the first end 301 and the second end 302 of each elastic piece abut a corresponding button 20 and the panel 10 respectively; a portion between the first end 301 and the concave part 303 of each elastic piece 30 is a fixed portion; a portion between the concave part 303 and the second end 302 of each elastic piece 30 is an elastic portion, namely the elastic supporting arm 304.
Flat springs in an arched structure provide an elastic force to bias the flat springs to arch in order to ensure structural stability, thereby facilitating assembly; during disassembly, press a middle part of each elastic piece 30 so that the concave part 303 thereof stops abutting a corresponding fitting base 21, and then pull out each elastic piece 30 to complete disassembly.
More specifically, a guiding incline 25 is provided for each button 20 between the fitting base 21 of the button 20 and the abutting position between the button 20 and the first end 301 of a corresponding elastic piece 30; when inserting each elastic piece 30 during assembly, the assembly process is smoother under the guiding function of the guiding incline 25.
Specifically, a position limiting structure is provided on each button 20 at the abutting position of the button 20 and the first end 301 of a corresponding elastic piece 30; more specifically, the position limiting structure is defined by a pair of first protrusions 22 formed integrally with each button 20 on two sides of the corresponding elastic piece 30 respectively. The position limiting structure effectively performs position limiting function and prevents deviation during assembly.
Preferably, in the present embodiment, a position limiting groove extending along a sliding path of each elastic supporting arm 304 is provided on the panel corresponding to the abutting position of the elastic supporting arm 304 and the panel 10; specifically, the position limiting groove is defined by a pair of second protrusions 12 formed integrally with the panel 10 on two sides of the corresponding elastic piece 30. The position limiting groove performs position limiting function and prevents deviation of each elastic supporting arm 304 on the panel 10.
Specifically, in the present embodiment, the panel 10 is provided with a front surface 101, and a rear surface 102 provided on a back side of the front surface 101; the buttons 20 and the elastic pieces 30 are provided on the rear surface 102 of the panel 10; accommodating windows 11 are formed on the front surface 101 of the panel 10 corresponding to positions of the buttons 20 for users to press the buttons 20 at the accommodating windows 11; certainly, in other embodiments, structures of the panel 10 and arrangement of the buttons 20 should not be limited to those disclosed by the present embodiment; for examples, if the buttons 20 are exposed beyond a lower part of the panel 10, users may press the exposed portion of the buttons 20 exposed beyond the lower part of the panel 10; or, the buttons 20 may be hinged to a lower bottom side of the panel 10, while the abutting positions of the elastic pieces 30 remain unchanged and the elastic pieces 30 still abut the rear surface 102 of the panel 10, functions such as pressing and resetting can also be achieved.
Furthermore, each button 20 is provided with a convex pressing part 24 extending towards a corresponding accommodating window 11 for users to perform pressing; in the present embodiment, in an initial state of the buttons 20 before being pressed, the convex pressing parts 24 flush with the front surface 101 of the panel 10 to provide a beautiful appearance, but certainly, it should not be limiting; in some other embodiments, the convex pressing parts 24 may, for example, protrude out of the front surface 101 of the panel 10 for the ease of pressing.
Furthermore, in the present embodiment, the rear surface 102 of the panel 10 is provided with blocking hooks 13 extending backwards; when pressing each button 20, each button 20 rotates backwards to a certain degree and abuts a corresponding blocking hook 13; therefore, rotating degrees of the buttons 20 are limited by the blocking hooks 13 to prevent damages of internal components caused by excessive pressing depth.
Furthermore, in the present embodiment, two hinging columns 23 are provided above each button 20 at two positions spaced apart from each other respectively; each button 20 is hinged to the panel 10 through two corresponding hinging columns 23; a corresponding elastic piece 30 is provided between the two corresponding hinging columns 23, so that the distribution of force is more even; during resetting of the buttons 20, each button 20 being hinged to the panel 10 through the two corresponding hinging columns 23 above the button 20 at the two positions spaced apart from each other respectively allows each button 20 to reset with the help of its own weight so as to achieve better resetting effect; certainly, in other embodiments, the hinging columns 23 of each button 20 may be located at other sides (i.e. left side, right side, or even lower side) of the button to achieve hinging; when the hinging columns 23 of each button 20 are located at the left side or right side of the button, resetting of each button 20 is fully relying on the elastic force of a corresponding elastic piece 30; when the hinging columns 23 of each button 20 are located at the lower side of the button, the elastic piece 30 of each button needs to also overcome the weight of the button 20, resulting in poorer resetting effect.
